SPECIFICATION forming part of Letters Patent No. 275,214, dated April 3, 1883,

Application filed December 9,1982.

- the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bronzing- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates especially to devices employed for applying bronze-powder to paper, 870., and has forfits object the production of a device wherein means and mechanism are employed whereby the quantity of bronze applied to the paper may be nicely and accurately regulated at will, and distributed in an even and uniform manner, the device being very simple in construction and easy to operate.

To accomplish this end my invention consists, essentially, in an inclosing case or box, wherein are located the mechanism for applying the bronze. v A feeding-table projects from one side of the inclosing-case, just below an opening therein. \Vithin the case are located two rollers, over which passes an endless apron, provided at a suitable point with grippingfingers for drawing in the sheets of paper, said fingers being operated by suitable cams within the case. Above the endless apron, in close proximity to the rollernextthe feeding-table, is a roller covered with for or similar soft material, said roller lightly touching the apron below and a feeding-roller above,having connection with the bronze-hopper, the various rollers having suitable gearing or pulleys attached to their shafts; and my invention also involves certain other novel and useful combinations or arrangements of parts, and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure l is a longitudinal sectional view of my device, showing the location and arrangement of the various interior parts, the position of the driving mechanism upon the exterior of the case being shown in the side elevation, Fig. 2.

Likeletters ofreference, wherever they occur, indicate corresponding parts in both figures.

A is the box or case inclosing the mechanism, said case having a narrow opening, a, at

each end thereof. A feeding-table, B, is located at the left of the case, upon which the sheets of paper to be bronzed are placed.

0 O are rollers extending across the case from side to side, an endless apron, D, passing thereover.

E is a roller covered with far or other soft material and placed above the apron in such a position as to touch it lightly.

Upon rollers G and E, within the case, are gear-wheels c and c, the same being connected by means of wheel F. Above roller E is located a roller, G, adapted and arranged to distribute bronze-powder from hopper H to the applying-roller E. Hopper H fits into the top of the case, as shown in Fig. 1, and is provided with a slanting bottom, It, the edge whereof, next to roller G, is provided with a flexible lip, It, which hugs roller G in such a manner as to permit only a thin film of powder to adhere to its surface while revolving.

1 is a gripping mechanism affixed to apron D, and operated by means of cams attached to the interior of the casing upon each side thereof. If desired, the gripping mechanism may be arranged with leaders to hold the paper in position while entering the machine.

Thepower for operating the machine may be applied by means of pulley J, rotated in the direction indicated by the arrows, Fig. l. Apron D communicates motion to roller 0, upon the outer endwhereof islocated a conepulley, K, a band, L, leading therefrom to a similar pulley, K, upon the shaft of roller G. ltollerM is rotated by its friction against roller U, and serves to assist the delivery of the bronzed sheets.

\Vhen constructed and arranged in accordance with the foregoing description, the printed or sized sheet of paper is fed to the grippers I and drawn beneath roller E, receiving the bronze therefrom, and upon passing beneath roller M the grippers are released, permitting the finished sheet to pass out through (6.

Having now fully described my invention, what I claim as new therein, and desire to se cure by Letters Patent, is-

1. In a bronzing-machino of the character herein specified, a hopper the bottom whereof 100 is placed at an angle, as set forth, and provided with a lip of soft material pressing against the distributingioller, substantially as shown and described.

2. The combination, with the hopper, the bottom whereof is placed at an angle and proand 0, bearing endless apron 1), provided with gripping mechanism I, applying-roller E, gear-wheels c e and F, distributing-roller G, and hopper H, the whole combined and ar- [5 described.

3. The combination, with hopper U, ofa distributing-roller, the speed whereof is variable, 10 substantially as shown and described.
